Yes, cats indeed possess a heightened sensitivity to odors compared to humans. Their olfactory system is highly developed, with approximately 200 million scent receptors in their nasal cavity, compared to around 5-20 million in humans. This heightened sense of smell serves several purposes for cats, including hunting prey, detecting predators, marking territories, and identifying other cats or animals.

Cats rely heavily on their sense of smell to navigate their environment and communicate with other cats. They use scent marking through glands located on their face, paws, and tail to establish territory boundaries and communicate with other cats.

Their acute sense of smell also influences their behavior and preferences, such as their food choices and reactions to different scents in their environment. Additionally, cats can detect pheromones released by other cats, which play a crucial role in social interactions and reproductive behavior.

Overall, the heightened sensitivity to odors is a vital aspect of a cat’s sensory perception, influencing various aspects of their behavior and interactions with the world around them.
